PHILIP T. DODGE, OF NEW YORK, N. Y., ASSIGNOR TO THE MERGENTHALE LINOTYPE COMPANY, A CORPORATION OF NEV YORK.

L|NoTYPE-MAc|-nNt-:.

SPECIFICATION forming part of Letters Patent No. 741,957, dated October 20, 1903. Application filed March 14; 1903, Serial No. 147,779. (No model.)

To a/ZZ whom it may concern:

Be it known that I, PHILIP T. DODGE, of NewYork, county of New York, and State of New York, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

My invention has reference to that class of linotype-machines in which a series of circulating matrices are employed, each matrix ro having in its edge a number of characters used one at a time. In this class of machines the composition of a line of characters is effected by selecting and assembling the matrices bearing the required characters and by adjusting the matricesendwse in relation to each other, so as to bring theselected characters, one on each matrix, into a common line.

The aim of my invention is to` provide a machine in which the matrices are suspended zo from and-arranged to travel on stationary inclined guides, which diverge at certain points in their length for the purpose of distributing the matrices and again converge-for the purpose of assembling or bringingtogether the z5 selected matrices.` :In 'this manner I am enabled to produce a machine combining the advantages of those machines in which single-letter matrices are suspended from and travel on fixed guides.

3o Referring to the drawings, Figure 1 is a perspective View of the machine from the front. Fig. 2 is a similar view from the rear. Fig. 3 is a top plan View illustrating the principal parts of the framework and guides.

Fig. 4 is a perspective view showing the relations of the inclined guides on which the matrices hang. Fig. 5 is a side elevation of the lower end showing the matrix-assembling mechanism. Fig. 6`is a crosssection on the 4o line 6 6, Fig. 5. Figs. 7, 8, 9, and 10 are views of details hereinafter described. Fig. 1l is a horizontal cross-section on the correspondingly-numbered line, Figs. 5 and G,il1ustrating the action of the assembling and transferring devices. Fig. 12 is a perspective View Figs. 13, 13", and 13c are particularly the mold and the devices forcon- 6o iningthe matrices in front of the same. Fig. 17 is a perspective view showing separated ifroin each other the parts for confining and justifying the line.

Fig. 17 is a perspective View of the support for the ejector and the :trimming-knives, this supportbeing a rigid part ot' the main frame. Fig. 17h is a crosssection on the correspondingly-numbered line 'of Fig. 17. Fig. 18 is a perspective view illustrating the mechanism for alining and ad- 7o justing the matrices in the casting position. Fig. 19 is a diagram of the justifyingand alining cams. Figs. 2O and 21 are diagrammatic views illustrating the action of the matrix alining and justifying devices. Fig. 22 is a perspective View of the melting-pot, the mold, and their operating connections, the mold being in position to permit the ejection of the slug. Fig. 23 is a perspective view showing the mold in casting relation to 8o the mouth of the pot. Fig. 24 is a perspective View, partly in section, illustrating the relation of the matrix-line, mold, pot, and adjacent parts just prior to their being locked together. Fig. 25 is a similar view showing 85 the parts locked together in the casting position. Fig. 2G is a perspective view of one of the escapements releasing the matrices. Fig.

27 is a perspective View of one of the matrices. Fig. 2S is a perspective view of one of 9o the spacers. Fig. 29 is a side elevation illustrating the relations of the inclined guides.

I employ as the basis of my machine a series of matrices Y, such as shown in Fig. 27, and a series of expansiole spacers or justifiers Z, such as shown in Fig. 2S. Each of the matrices consists of a bar, of brass or similar material, having in one edge a number of diierent intaglio characters or matrices proper', y, in the opposite edge a series of rco hook y2, by which the matrix is suspended from the stationary guides in the main frame.

I employ any suitable number of matrices, usually from one hundred to three hundred. They are divided into groups. All the matrices in one group are of the same length and have in one edge ten diiferent characters or matrices proper, y, of equal width. The matrices belonging to different groups contain different characters and are made of different lengths. If the machine is adapted to produce ninety characters, as usual, there will be nine groups of matrices, those of eachgroup containing ten characters. They are made of uniform size and width at their lower ends. The difference in length is due to their elongation at the upper end a greater or less distance beyond the characters. This variation in length is utilized in effecting the proper distribution of matrices of the differentgroups to their sustaining wires or guides. When a line is to be composed for use at the moldit is necessary,'iirst, to select in their proper order matrices or matrix-bars bearing the required characters in the order in which the characters are to appear; second, to assemble these matrices in line side by side, and, third, to adjust them endwise in relation to each other, so that the designated characters or letters (one in-each matrix) will appear in a common horizontal line. The spacers Z consist each of an upper member a', having a sustaining-hook at the upper end and a dovetail groove in one side, and of a lower member e' in the form of a wedge, arranged to slide inthe groove in the upper member. The two parts are inserted in the line of matrices and form jointly an expansible spacer the thickness of which may be increased by sliding the lower member upward through the line alongside of its companion, the action in this respect being the same in principle as that of the spacers commonly used in the commercial Mergenthaler linotype-machine of the present day.

Passing now to the machine in which the matrices and spacers are employed its purpose is to sustain the various groups of matrices, release the individual matrices as indicated by the finger-keys and assemble them in a common line, adjust the individual matrices longitudinally to aline the selected 'characters, transfer this line to the casting mechanism, effect the justification of the line against the mold, supply the mold with mol' serve at the points indicated. It will be observed that the two bottom guides C (J extend downward and forward from the points at which the matrices are suspended in converging lines until the space between them is just sufficient t0 admit the matrices. From this point they are continued forward and downward in parallel lines to the point 2 2 and thence with a sharper inclination to the point 3 3, whence they are continued downward and to the right and turn rearward and upward until they arrive at the point 4 4, where the casting mechanism is located. The guides C C2, &c., lying at successively higher levels, also incline downwardly and forwardly in converging lines, their lower'ends terminating directly over the bottom guides C and at a slight distance therefrom, as shown in Figs. 13 and 29, so that the matrices descending successively on the upper guides will have their eyes or hooks delivered therefrom to the bottom guides C C, upon and between which a series of matrices assembled or composed in line will be free to slide downward and forward. In other words, .a matrix released on either of the guides will slide downward and forward by gravity until it finally passes between the bottom guides C C, onone or the other of which it will remain suspended. A series of matrices thus released and containing the characters to appear in aline of print will pass downward and forward between the guides C C. A

Before presentation to the mold it is necessary that the longitudinal adjustment of the matrices shall be effected. This is accomplished, as shown in Figs. 4, 13, and 29, by shortswitches or guides D, lying above but normally to one side of the bottom guides C. There are two similar sets of switches, one for each side of the machine. Each switch consists of a short inclined wire or rod, which when moved laterally into operative position will form a junction with one of the adjacent guides C, so that a matrix descending on either of these guides will ride at its upper end on a switch, from which it will be suspended,so that as the matrix passes downward it will be sustained and carried to a guidewire at a level higher than that at which it would have been carried on the bottom guide. The switches communicate with and deliver the matrices to stationary guides E, arranged in upright parallel banks or tiers, the number of these guides corresponding with the number of letters on one matrix. A matrix is delivered by the appropriate switch to one or another of the guides and carried thereby at a higheror lower level, according as one character or another of the matrix is required for use. If a character at the lower end of the matrix is demanded, the uppermost switch will be thrown into action and the descending matrix will be delivered to the uppermost guide, the effect of which will be t-o raise the bottom character tothe alining or casting level. If, on the other hand, a character at ICO ITO

a higher level on the matrix is-demanded, the matrix will be switched onto a guide at the appropriate height. The result of this procedure will be to assemble the matrices side by side in a common line between the guides E at different heights or elevations, so that the designated characters will appear in a common line. After the line is thus assembled, suitable spacersbeing introduced at the proper points in the same manner that the matrices are introduced, the entire line is moved bodily downward between the guides and thence to the right and finally upward to the casting-point indicated in Fig. 4E, their relative positions or adjustment vertically being maintained until after the slug is cast against them. After the casting action the matrices are released and permitted to drop until their lower ends stand at a common level. The upper ends of matrices belonging to different groups will of course stand at different levels or heights, as indicated in Fig. 4. The line is now carried upward and rearward and the eyes or ears lof the matrices caused to engage over the fixed guides F, arranged at different levels and in two vertical tiers. These rguides are continued upward and rearward and then continued downward, as shown at 5 5, Fig. 4, in diverging lines until they connect with the converging guides on which the matrix groups are stored. After the matrix-line has been carried upward and returned toward the front at the top of the machine the matrices will descend by gravity on the diverging guides and each matrix will join the group to which it originally belonged.

This method of distributing the matrices by gravity on the diverging guides to the upper ends of the converging guides is essentially the same as in United States Patent to J. R. Rogers, No. 679,481.

Having thus described the general arrangement of guides for assembling the matrices, adjusting them longitudinally, and thereafter distributing them, I will now describe the details of the machine.

The stationary guides are all mounted in a rigid main frame A, which may be of any form and construction adapted to sustain the various operative parts. They consist, as shown more particularly in Figs. 8 and 10, of sections of wires of suitable length sustained and joined end to end by clips or plates d, which are in turn supported on upright rods informing part of the main frame aud separated from each other by intervening washers or collars c. The ends of the clips or plates are bent upward and curled into tubular form. The ends of the wire or guide sections are reduced to form necks or tenons which are inserted into the tubular portion of the plates and secured therein after the manner of the guides in the Rogers patent before referred to. It will be observed that under this construction the sustainingplates form continuations of thewires, so that a smooth unbroken su rfacc 132 13", and 13.

is provided on which the eyes of the matrices may travel.

The groups of matrices are held at rest in the storage positions by escapements G, such as shown in Fig. 26, each consisting of two vertically-reciprocating dogs g g', pivoted at their upper ends to the opposite extremities of a lever g2, which is mounted on a central pivot g3 on a fixed bracket or support g4. The dogs or pawls g g are notched at their lower ends to straddle the guide-wire in advance of the matrices, whereby they are prevented from sliding downward. Normally the lower dog stands in front of the foremost matrix. When the actuating-lever is moved, the rear dog g is pushed downward behind .the foremost matrix to hold those lying in the rear, while at the same time the forward dog g is raised to permit the escape of the foremost matrix. The rising and falling motion of the two dogs alternately permits the matrices to slide one after another down the guide to the point of assemblage or composition.

The various escapements are connected each by a wire g5 to a plate actuated by a finger-key H in the keyboard.' Each of the nger-keys has two functions, rst, that of operating the escapement to release the matrix bearing the selected character, and, second, to throw into action the appropriate switch D, that the matrix may pass to the line at such height as to present the selected character at the alining level. These results are accomplished by mechanism shown in Figs. Each matrix contains ten characters. Infthe keyboard there are on `each side five rows of keys extending from right to left, and in each row there are eight Inother words, there are ou each side of the keyboard forty keys representing the forty matrix characters 011 that side of the machine. The two sides of the keyboard are builtin duplicate, except that the parts are reversed right and left, and the following* description of one side will answer for the other. Each of the switch-wires D in the one side of the keyboard is attached rigidly, as shown in Fig. 13, to one end of a bar d, extending horizontally across the keyboard from side to side and free to move endwse a distance sufficient to throw the switch laterally into and out of its operative relation to the guide on which the matrices descend. Each of these bars d is formed in the upper edge with a series of beveled lips d in position to be acted upon by all the iinger-V keys in one row from right to left. The finger-keys are each provided with a stem or spindle vertically guided in the frame and having at the lower end a beveled surface to act upon one of the lips d of one switch-bar. The keys in the transverse rows are arranged each to move the appropriate switch-bar d, so as to bring into action that switch which is necessary to arrest the released matrix at the proper height to bring in to action thefpar-
